/* ==========================================================================
   slide-fx-picker.css — THIẾT KẾ LẠI HOÀN TOÀN bộ chọn hiệu ứng.
   ---------------------------------------------------------------------
   Bản cũ: 2 khối <select> nâng cấp thành 2 lưới icon MỞ ĐỘC LẬP, cùng lúc,
   ngay dưới thanh công cụ -> chiếm gần hết chiều ngang, nhìn rối và "vỡ"
   bố cục (đúng như ảnh chụp bị phản hồi là xấu).
   Bản mới: 1 THANH GỌN (tw-fx-bar) chỉ hiển thị 2 "viên thuốc" (pill) tóm
   tắt hiệu ứng đang chọn -> bấm vào mới mở ra ĐÚNG 1 HỘP THOẠI (tw-fx-modal)
   chia rõ 2 TAB "Chuyển slide" / "Nội dung xuất hiện", không bao giờ có 2
   lưới icon hiển thị chồng nhau cùng lúc nữa.
